We have expectations from ourselves to be rational beings, maybe with very few exceptions. We certainly have these expectations from everybody else. This is most visible at the organizational level. People HAVE TO behave rationally/reasonably/logically. We expect us, but mostly everybody else, to analyze the situations objectively, decide rationally the course of action and then implement it according to the plan. We expect to be computing machines that use predictable and accurate algorithms and operate with little or no flaw.
